MAGAZINE-PENCIL.

Specification of Letters Intent.

Patented Dec. 23, 1919.

Application filed June 11, 1918. Serial No. 808,981.

To all whom it may concem:

Be it known that I, Loonum J. llr. fosr, a citizen of the United States, resldmg at New York in the county of New York and State of hiew York, have invented certain new and useful Improvements in Me Pencils; and I do hereby declare e following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in magazine pencils and has particular reference to the general type of pencil embodled 16 in my co endin application, filed August 22 1918, erial 0. 251,457.

The objects of the invention are to provide a pencil as described which will embody in its construction, a simple means whereby perfect alinement or register of the parts is assured when thgfiare secured 120- gather after filling and re ngrand to provide means whereby the supp leads may be thrust simultaneously from t e magazine to a point sufiiciently removed from the writing end of the casing to rmit the leads to be easily grasped and inserted in proper relation to the lead-projecting mechanism.

These objects are accomplished in the device disclosed in the accompanying drawings, in which similar reference numerals designate similar parts and in which Figure 1 is a view showing the pencil in use;

Fig. 2 is a longitudinal section, enlarged, through the penci A Fi 3 is a detail view of a part which willie slightly reinafter be termed the feeder;

some of the parts d1sassembled,'and Fig. 5 is a fragmentary elevation of the lower extremity of the pencil illustrating the manner of projecting the leads.

I Referring, in detail, to the parts, 1 designates an outer casing. 2 is a corrugated magazine barrel which is secured concentrioall within the casing and embraces a helica y grooved tube or feed operating member 8. The member 8 is secured to a tube 4 forming a part of a cap 5 held upon easing 1 in'such manner as to be capable of rotation thereon. A guide and lead-containing c linder 6 is held Bl within thetube 3 which tube extends upzine- Fig. 4 is an enlarged perspective view of proximately the length of the shell and is provided with a longitudinal slot 7 and a ug 8 acting to retain the cylinder 6 in its pro or POSltiOIl.

ithln the lead-containing cylinder is a er or propelling bar 9 having a uniform thickness throughout-its length and formed with a pair of offsets 10 whlch function in alternate grooves of the tube 8 and enlgafie through and along the slot 7 in the ea 66 containing cylinder.

n inner nozzle 11,

tapered at its outer extremity and formed with a threaded portion 12 at its inner proximal end, enga over and is attached to the outer end of 7 e 10 lead-containin cylinder. This inner nozzle has soldered tfiereto a multi-sided extension 13, which virtually constitutes the distal end of the nozzle, and each side of which snugl engages the corresponding innermost wall of 76 each corrugation of the barrel with the angle between any two adjacent sides of the extension disposed intermediate the outermost wall of each =corru ation. Provision is thus made for connecting the nozzle 11 with the barrel in an extremely rigid manner, and having established such rigidity, a perfect fit between the inn 1- terminal of outer nozzle 14 and the adjacent terminal of casing 1-as at 11. Outer nozzle 14, tapered at one end and internally threaded at the other, engages the threaded portion of the inner nozzle and acts as a closingmember for the magazine section. e magazine is defined by the inner wall of the shell and the outer walls of the corrugations of the barrel. In each corrugation, a lead 15 is held in reserve, while the active lead is maintained axially of the cylinder 6 and the nozzle 11. As ,the lead is W5 point isfed o wardly by turning the cap and the opera ing member 3, the grooves of which, upon engaging the ofl'sets 10, will constrain the feeder outwardly and thus force the lead out of the holder. It is obvious that an opposite turnmg movement of the cap will draw the odor inwardly.

s explained at length in my co ding application, when it is desired to insert a new lead, the outer nozzle 14 is removed and the end of the inner pozzle is ta ped against the'hand or other object. In this position, as exhibited in Fig. 5. all of the leads in the magazine will partially gravitate from the 110 consumed, the

magazine simultaneously, being projected outwardly substantially coextensive with the end of the inner nozze 11. Then upon slightly elevating the Writing end of the encil, any one of the leads may be withdrawn and inserted in the inner nozzle. The outer nozzle is replaced and the user roceeds to adjust the new lead for writing.

he important oint to bear in mind is that no matter how ragile the leads may be, they are preserved intact because the end of the nozzle receives and absorbs the impact, the nozzle strikes the object first, and the leads follow. Furthermore, the screw-threaded base 1:! of the nozzle serves as an extended bearing for the leads; that is, a bearing in addition to the one afior ed by the mag?- zine. This is important, too, for when t e leads have been projected as illustrated in Fig. 5, and the tips of the fingers are glaced in a position to grasp one or the lea s, the space is so limited t at a slight flexing of the two adjacent leads is bound to ensue, and were it not for the presence of this extended bearing, the leads would be broken quite frequently.

Having thus described this invention, 1 claim:

1. A pencil having the combination of a casing, mechanism therein for projecting the lead, a. longitudinally recessed lead supply barrel, open at the writing end, a nozzlehaving a screw-threaded proximal end and a multisided distal end, and a closure for the open end of the barrel engageable with said threaded end of the nozzle, said multlsided 0nd of the nozzle being rigidly secured with in said barrel.

2. A pencil having the combination of a casing, lead rojecting mechanism therein, a longitudina corrugated, tubular lead su ply barrel open at the writing end, a nozz e havin a screw threaded proximal end and a mu isided distal end, and a closure for the open end of the barrel on ageable with said threaded end of the nozz e, said multisided end of the nozzle bein receivable within the end of the barrel an the angles of the said distal end of the nozzle project ing into the corrugations of the barrel.

3. A pencil having a casin provided with an annular reservoir adapte to hold leads, a nozzle extending from said casing having a portion thereof smaller than the interior periphery of said reservoir, means on said nozzle forming a continuation of the interior wall of said reservoir whereby leads when slid from the reservoir spaced from the small portion of the nozzle to facilitate their being graspe by the fingers, and a closure member for said reservoir.

4. The device of claim 3 in which the means comprise an enlarged shank portion provided on the nozzle.

5. The device of claim 3 in which the means also coact with the closure member to keep the latter in place.

6. The device of claim 3 in which the closure member and means are threaded and coact with each other to keep the closure member in place.

7. A pencil having a casing provided with an annular reservoir adapted to a nozzle extending a portion thereof smaller than the interior periphery of said reservoir, whereby leads when slid from the reservoir will be thereby spaced from the small portion of the nozzle to facilitate their being asped by the fingers, and a closure mem r for said reservoir.

In testimony whereof I aflix in signature.
